[counterintuitive] Does adding 'Let's think step by step' improve coding accuracy?

Drop generic Chain-of-Thought triggers. Use structured scratchpads or API-native reasoning models for complex tasks, and direct zero-shot for simple tasks.

Journey Context:
'Let's think step by step' was a zero-shot CoT breakthrough for GPT-3. Modern instruction-tuned models already internalize step-by-step reasoning by default. Forcing it on simple tasks causes over-thinking and confabulation. For complex tasks, generic triggers produce unstructured, rambling text. Modern replacements are either API-level reasoning models \(o1\) or structured tags \(e.g., think here\) that separate reasoning from output cleanly.
